Played the demo recently. It was really nice, expecially all the little tweaks from the first game that make everything smoother and easier to understand. Waiting eagerly for the rest now :)
Maybe it's the same problem as mine? If I launch the game from the Itch app, whith sandboxing enabled, it won't run. But if you launch the game directly from the installation folder (nw.exe), it runs just fine.
